Picking battles wisely: plant behaviour under competition   总被引:2,自引:0,他引:2  
Plants are limited in their ability to choose their neighbours, but they are able to orchestrate a wide spectrum of rational competitive behaviours that increase their prospects to prevail under various ecological settings. Through the perception of neighbours, plants are able to anticipate probable competitive interactions and modify their competitive behaviours to maximize their long-term gains. Specifically, plants can minimize competitive encounters by avoiding their neighbours; maximize their competitive effects by aggressively confronting their neighbours; or tolerate the competitive effects of their neighbours. However, the adaptive values of these non-mutually exclusive options are expected to depend strongly on the plants' evolutionary background and to change dynamically according to their past development, and relative sizes and vigour. Additionally, the magnitude of competitive responsiveness is expected to be positively correlated with the reliability of the environmental information regarding the expected competitive interactions and the expected time left for further plastic modifications. Concurrent competition over external and internal resources and morphogenetic signals may enable some plants to increase their efficiency and external competitive performance by discriminately allocating limited resources to their more promising organs at the expense of failing or less successful organs.  相似文献

The present study examined whether women's testosterone levels are influenced by being with a sexual and romantic partner after a period of sexual abstinence. Women in long distance relationships (n = 15) provided five saliva samples: at least 1 week before seeing their partner (and at least 2 weeks since their last visit), the day before seeing their partner, when they were with their partner but prior to engaging in sexual activity, the day after their first sexual activity, and 3 days after they were separated from their partners. Salivary testosterone was lowest when participants had been away from their partners for at least 2 weeks and highest the day before they were to see their partners and the day after sexual activity. Results from this study indicated that women's testosterone increased both the day before they were with their partners and they day after they first engaged in sexual activity. However, something about initially reuniting with their partners returned their testosterone to baseline levels, which may be an effect of being in the same location as a partner, or just a state fluctuation due to nervousness or other psychological state.  相似文献

Moshe Shokeid 《Ethnos》2013,78(2):219-238
Ethnographic texts preserve the historicity and losses of both the people observed and their observer. However, anthropologists rarely inform their readers about the circumstances of their departure from a fieldwork project. Without formally indicating the completion of their research goals, they usually move on to a new field and cease publishing on their former site. This procedure seemed natural enough when anthropologists conducted their studies in remote Third World locations. The constraints of distance, time, and budget made that abrupt separation seemingly inevitable and self-explanatory. But when anthropologists choose fieldwork sites that are close to home or easy to revisit, or conduct long-term research, their relationships with their subjects change radically, both during fieldwork and during the stages of writing and publishing the ethnographic text. Consequently, their eventual exit from the field involves a different process. Based on the experience of a fifteenyear engagement in the study of a gay synagogue in New York, this paper explores the latter process. The issue of exiting presents a methodological, emotional, and ethical problem meriting serious professional consideration.  相似文献

OBJECTIVE: To discover cancer patients'' views about disclosure of information to their family, their family''s influence over the information given them, and their preferences for doctors'' behaviour if they and their family disagree, as a complement to applied ethical theory. DESIGN: Semistructured interviews followed by qualitative content analysis. SETTING: Mainly urban British general practice. SUBJECTS: 30 patients in whom cancer, excluding basal and squamous cell skin carcinomas, was diagnosed 1-7 years earlier. RESULTS: All subjects wished doctors to respect their views rather than those of their family, should they differ. With their consent, subjects favoured close family receiving information about their illness, all but one mentioning advantage to their family. Without such consent, six unconditionally favoured disclosure of information to their family while seven unconditionally opposed disclosure. Seventeen participants restricted their approval for such disclosure to specific circumstances. Only two participants approved of their family influencing the information that they received about their illness; all but seven wished to receive full information, the exceptions relating to information about bad prognosis. CONCLUSIONS: Subjects favoured openness with their family but most rejected unconditional disclosure of information without their consent and their family influencing what information they would be given. They valued respect for their autonomy more highly than beneficence and considered that their own needs took priority over those of their family.  相似文献

ABSTRACT

We critically review and discuss several methodological problems with their analysis. Their definition of the occupational hierarchy is unclear, and their inadequate statistical models exacerbate the vagueness of their results. They ignore gender interactions, and the age range of their target population seems too narrow for their research concerns. Their interpretation of their own statistical findings on occupational attainment is fundamentally flawed although they refuse to acknowledge it. Their reported results cannot be replicated based on the information that they are willing to reveal about their analysis which suggests additional, undisclosed errors. In our reanalysis of their data using more appropriate methods, we find that rather than being systematically disadvantaged, the occupational attainment of most second-generation Asian Americans has either achieved parity with whites or has exceeded them after controlling for age, educational level, and survey year.  相似文献

噬菌体和它们的宿主菌组成了地球上教目最庞大的微生物种群,噬菌体靠寄生宿主菌来扩增繁衍。但在漫长的进化中,噬菌体与宿主菌间不单是捕食关系,它们间还形成了复杂的相互对抗机制,其中抵抗防御机制的抗防御机制也会促使抗.抗防御机制的产生。从生态学角度来看,噬菌体和宿主菌间的共进化保持着动态平衡。本文综述近年来这一领域的研究,为更清楚地了解噬菌体与宿主菌间的关系和应用提供了参考。  相似文献

The ability to perform predictive genetic testing of children raises ethical concerns regarding whether and when to test and the disclosure of results. Semi-structured interviews with a convenience sample of pediatricians (12) and geneticists (13) were conducted to see how they would react to parental requests for predictive genetic testing of their children, and their attitudes about testing their own children. We also asked about disclosure attitudes and practices for their patients' relatives and within their own families. Respondents would provide predictive genetic testing for most conditions, yet were less likely to seek this information about their own children. Respondents believed it was very important for patients to share some types of genetic information with relatives, and were directive in their counseling about intrafamilial disclosure, especially within their own families. Although respondents would almost never breach patient confidentiality, many would breach confidentiality within their own families. Health care professionals distinguish between their professional and personal roles with regard to issues of access and confidentiality in predictive testing of children. They are willing to provide greater access and more confidentiality for their patients than within their own families.  相似文献
